HYDROTREATING DESIGN CONSIDERATIONS
Catalyst
• Efficient hydrogen consumption and removal of impurities
• Minimize material costs over expected lifecycle
Reactor Internals
• Flow distribution to minimize radial temperature fluctuations
• Extension of catalyst life and capacity for increased feed rates
Metallurgy Selection
• Limit or prevent stress corrosion cracking
• Decrease downtime required for neutralization of acids
Impurity Removal
• Optimal catalyst reaction of sulphur, nitrogen, oxygen, and aromatics
• Demetallization prevents catalyst damage and maintains life expectancy
Hydrogen Consumption
• Recycled hydrogen and required make up rate
• Distribution of hydrogen to optimize mass transfer
